Experts have described the Stamford Diversion Canal (SDC) and the Stamford Detention Tank (SDT) as welcome moves in lowering the risk of floods in the Orchard Road area, though they added that the science of flood management remains extremely difficult.

For instance, Assistant Professor Aron Meltzner of Nanyang Technological University's Earth Observatory of Singapore (EOS) said it is almost impossible to calculate how much worse the rainfall would have to be - than that in 2010 and 2011 - to overwhelm the two new works and lead to floods.
